(d) Subsp. sphacelata (C. Presi) R. Fernandes , Bot. Jour. Linn. Soc. 70: 12 (1975)

( A. sphacelata C. Presi ):

Biennial (or perhaps sometimes perennial). Stems up to 30 cm, from a woody stock, rigid, simple or more or less branched. Leaves not more than 2(-4- 5) cm, pectinate-laciniate at base. Involucral bracts often with brown scarious margin and apex. Receptacle 2-5 x 2-3 mm, shortly conical; scales oblanceolate, abruptly acuminate, rigid. Ligules 3 - 5-6-5 x 2-25-3 mm. Tubular florets sometimes purple. Mountain pastures. • S. Italy, Sicilia.

Plants from Corse referred to subsp. arvensis var. humilis Gay ex Rouy perhaps belong to subsp. (d).

A. brevifolia Lojac. , FZ. Sic. 2(1): 81 (1902), described from Sicilia, is probably only a variant of 27(d) with longer, diffuse stems, leafy to the apex.
